Abstract: The present description discloses a method for performing network selection and traffic routing by a user equipment (UE). The method can comprise the steps of: a non-access stratum (NAS) of the UE receiving from a mobility management entity (MME) an indication, for wireless local area network (WLAN) offloadability for a first public data network (PDN) connection, and information about a network-based IP flow mobility (NBIFOM); the NAS of the UE determining whether or not a collision exists between the indication and information; the NAS of the UE deciding for a suspension of the NBIFOM on the basis of the existence of collision; and the NAS of the UE transmitting to a PDN gateway (P-GW) a message or information, notifying the suspension of the NBIFOM, on the basis of the decision for the suspension of the NBIFOM.

Abstract: A method for transmitting and receiving data in a wireless communication system, and a device therefor are disclosed. Particularly, a method for transmitting downlink data in a packet data network gateway (P-GW) in a wireless communication system can comprise the steps of: receiving, from an application server, downlink data in which an Internet protocol (IP) header including an IP address of a terminal is encapsulated; removing the IP header from the downlink data; and transmitting, to a serving gateway (S-GW), the downlink data from which the IP header is removed through a bearer identified by the IP address of the terminal, so as to transmit, to the terminal, the downlink data from which the IP header is removed.

Abstract: A method for managing an area of a terminal in a wireless communication system and an apparatus therefor are disclosed. Specifically, a method for performing, by a terminal, location area update in a wireless communication system may comprise the steps of: transmitting, to a network node, a first request message including an additional cell list comprising one or more neighboring cells of a serving cell of the terminal; receiving, from the network node, a first accept message including information indicating acceptance of the use of the additional cell list; and, when a changed serving cell of the terminal belongs to a tracking area configured to the terminal and does not belong to the additional cell list, performing a cell-based area update procedure.

Abstract: A method for transmitting and receiving a signal related to monitoring by a Service Capability Exposure Function (SCEF) in a wireless communication system is disclosed. The method includes receiving, from a Service Capability Server/Application Server (SCS/AS), a first request containing first information related to deletion for a monitoring configuration; transmitting, to a Home Subscriber Server (HSS), a second request containing second information related to deletion for the monitoring configuration, wherein the second monitoring request contains information indicating whether the second monitoring request is a request for deletion of all monitoring configuration of a subscriber.

Abstract: A method for resuming an RRC connection performed by a UE in a wireless communication system may include entering an EMM-IDLE mode with a suspend indication as the RRC connection is suspended; generating an initial NAS message when a procedure using the initial NAS message is triggered; requesting a resume of the RRC connection from an upper layer of the UE to a lower layer; and switching from the EMM-IDLE mode with the suspend indication to an EMM-CONNECTED mode when the upper layer receives an indication that the RRC connection is resumed from the lower layer.

Abstract: A method of transmitting data and an eNB are disclosed. The method of transmitting data, which is received from a user equipment and transmitted to a network entity by an eNB, can include the steps of receiving a data packet of the user equipment from a first layer different from an IP layer of the eNB in the IP layer, checking whether or not the data packet corresponds to a data packet transmitted by the first layer using a header of the data packet, if the data packet corresponds to the data packet transmitted by the first layer, adding an IP header selected using a pre-stored mapping table to the data packet, delivering the data packet to which the IP header is added to a second layer corresponding to a lower layer, and transmitting the data packet to which the IP header is added to the network entity.
